TRUSS.

Specification of Letters Fatent.

Patented May 9, 1915.

Application filed May 3, 1915. Serial No. 25,523.

To all/1.071072@ it may concern Be it known that IQVALTER T. Bono, acitizen of the United States, residing at Battle Creek, in the county ofCalhounr and State of Michigan, have invented certain new and usefulImprovements in 'Trusses, of which the-following is a specification.

This invention relates to improvements in trusses. f i

The mainobjects of this invention are to provide in a truss animprovedelastic belt and one in which the elastic kportions are verystrong and do not deteriorate in use, and further, one in which the mainbody of the belt yis non-elastic, and the elastic portion is confined toa small areaadjacent the pad.

Further objects, and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish the objects of mylinvention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims. y

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which: j

Figure I is a front perspective view of a truss embodying the featuresof my invention. Fig. II is an enlarged 'detail front l elevation, thehousing-'for one of the spring devices being broken away to showthearrangement of the parts. 'Fig III is a detail longitudinal section on aVline corresponding to line B-Bof Fig. II. Fig. IV is an enlargeddetailed section corresponding to that of Fig. III, showing structuraldetails.

In the drawings, similar reference characters rrefer to similar partsthroughout the several views. y

Referring to the drawings, the pad 1 is preferably that of the MillerPatent No. 1.133,815, issued March 20, 1915. As its structural detailsform no part of this invention they are not further .described herein.

A back piece 2 preferably of relatively stiff material is secured to theback of the pad by the screw 3 which is arranged through the rear wallof the pad and threaded into a retaining plate A arranged therein. Thebody belt 5 is formed of nonelastic material.

On the rear of the back piece 2 I arrange an elastic strap 6, the strapbeing secured by the clip plate 7 which is retained by the screw 3. Theclip engages the strap centrally so that both ends are free. Sets ofcoiled springs 8 are provided, the springs being provided with crossbars 9 at their inner ends and cross bars 10 at their outer ends. Thecross bars are provided with lugs 11 upon which the end coils of thesprings are threaded or otherwise secured. The cross ybars 9 areprovided with keyhole slots 12 adapted to engage the screw 3 which isprovided with a stud portion 13, the screw having a collar-likeenlargement 14 engaging the clip, there being sufiicient space betweenthis collar and the head of the screw to constitute an attaching studfor the cross bars 9. One of the cross bars 9 is provided with a springtongue 15 arranged over the slot and adapted to engage the stud, asshown in Figs. II, III and IV. The outer cross bars 10 are provided withbelt connecting buckles 1G, the buckles being pivotally connected to thecross bars at 17.

The elastic strap 6 is secured to the outer cross bars at 10 by means ofthe studs 18. The strap Gis preferably provided with ya series ofopenings 19 adapted to receive the studs 18 so that the elastic strapmay be adjusted. l

Loop-like housings 20 for the spring connections are provided. Thesehousings are carried by the back piece. The strap 6 and the springs andthe connections therefor are entirely freefrom these housings so as tomove freely therein.

The springs are so arranged that they do not come in contact with thebody of the wearer. The elastic strap is also protected, but should itdeteriorate and become yineffective it ymay be renewed. The coiledspringconnectionl is quite satisfactory without the elastic straps. butI prefer the combination kas I have illustrated andkdescribed.

The elastic or resilient portion or connection of the belt is providedin a small area and is very effective and durable in use.

The drop strap 21 is provided with a belt engaging loop 22 at one endand with a clip arnet onirica. l

, other lend. l

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent, is:
